"It is said that there are no sudden changes in nature, and the common view has it (meint) that when we speak of a growth or a destruction (Entstehen oder Vergehen), we always imagine a gradual growth (Hervorgehen) or disappearance (Verschwinden). Yet we have seen cases in which the alteration of existence (des Seins) involves not only a transition from one proportion to other, but also a transition, by a sudden leap, into a quantitatively, and, on the other hand, also qualitatively different thing (Anderswerden); an interruption of the gradual process (ein Abbrechen des Allmählichen), differing qualitatively from the preceding, the former, state."
